Yes, we sent out notice yesterday that once migrated, we would be running a full refresh. This is necessary because the migration of terabytes of data was taking too long, so instead, it was necessary to re-capture roughly a million screenshot requests.
Hello! I know you are undergoing a server migration, but I wanted to let you know that all of my older thumbs are no longer working and are showing the "thumbnail queued" thumb. For example, http://www.shrinktheweb.com/xino.php?embed=1&stwu=[secretkey]&STWAccessKeyId=[accesskey]&Size=&stwUrl=http%3A%2F%2Feliza-bennett.com%2F was originally created on Jan. 24 and http://www.shrinktheweb.com/xino.php?embed=1&stwu=[secretkey]&STWAccessKeyId=[accesskey]&Size=&stwUrl=http%3A%2F%2Femilybluntfans.com was created yesterday.
Is this due to the migration? Or is something else going on?
